Flashed the ROM. Want to thank everyone who worked on it - it's great. 

Unfortunately, battery drain, as was my experience with every Kasty ROM, is nothing short of execrable. About one per cent every minute - I kid you not! Two things still work in its favor: battery drain MUCH lower during sleep, and the ROM overall is so much better, that it can be overlooked for now.

Still, any advice on the matter will be greatly appreciated, up to and including replacing the battery.

Speaking of which: what wrench/screwdriver do you need to open up the tablet? The screws are so small, I can't even decide if they are Torx or Allen, let alone what size they are... Again, help will be appreciated.

Thanks again!
